Original application filed August 5, 1911, Serial No. 642,544. Dividedand this application filed il'am'mryv 21, 1915, Serial No. 3,591.Renewed November 1, 1915. Serial No. 59,148.

To all whom it may concern:

Be it known that we, GLENN S. WILLIAM- SON and CHARLES E. MANDELICK,citizens of the United States, and residents, respectively, of New York,borough of Manhattan, county and State of New York, and Ridgefield Park,county of Bergen, State of New Jersey, have invented certain new anduseful Improvements in Margin-Regulating Mechanism for Web-Rolls, ofwhich the following is a specification.

This invention relates to web guiding mechanism and to margin-regulatingmechanism for web rolls, and the subject-matter hereof constitutes adivision of our application filed August 5th, 1911, Serial No. 642,544,now Patent No. 1,160,556, Which application is directed moreparticularly to means for maintaining a uniform tension on the web, thesame including a braking electric generator driven by the Web.

The object of this invention is to produce a simple and effectivemechanism whereby accurate axial adjustment of the web roll mav beeffected to keep the web running true and thereby preserve uniformmargins.

A further object is to combine such mechanism with the connections fordriving the generator, so as to produce a unitary apparatus that can beconnected with and disconnected from one end of the web roll' spindle,thus making possible a compact and advantageous arrangement andpermitting ready replacement of the web roll and spindle.

A further object of the invention is to provide a simple and efficientmechanism whereby accurate adjustments of the web roll may be effectedin .printing presses so -as to preserve uniform margins and to regulatethe margins of the web with relation to a printing couple of the press.

To these ends the invention comprises the parts, improvements andcombinations herein described and illustrated in their preferred formsand more particularly .pointed out in the appended cla1ms.

In the accompanying drawings showing the preferred embodiment of theinvention: Figure l is a plan view, partly broken away and partly'insection, showing the applica-. tion of the invention to aprinting-press, the cover being removed from the braking tion on anenlarged scale, the plane of the section intersectin the axis of the'webroll;

tail in the aforesaid application and need not here be set forth withthe same detail.- It comprises an electric generator 11,the armature ofwhich is drlven by the roll spindle 8 and the fieldof which is floatingor rotatable so as to be turned by the torque of the armature. The fieldframe 12, as it turns, by means of a gear ring 13 which it carries,operates a suitable rheostat not The; brake mechanism" shown isillustratedand described in deshown) to cut resistanceprogressively into1 I the armature circuit, so that the braking effect. of the generatoris diminished as the roll decreases'in size and its angular" velocityincreases. Since the' progressive introdu'ction of resistance into thearmature circuit diminishes the drag of the. armature on the field,means are provided for opposing decreasing resistance to the turning ofthe field by the armature, an embodiment of which means comprises asuitable cam 14 turned by the field frame through gears 15, 16, andacting on a flexible connection 17 to raise a lever 18 carrying a weight19.

All of this is fully set forth in our prior application, to whichreference may be had for details. p

The armature of the generator is driven from the spindle 8 by a. clutch20, a telescopic shaft 21, a gear 22 on the end of said shaft, and apinion 23 on the armature shaft and meshing with said gear. The clutchis preferably a magnetic clutch, and comprises a conical electromagneticmember 24: at the other end of thetshaft and a concave conical armaturemember 25 fixed to the end of theroll spindle. The coils 26 of theclutch are supplied with current from any 21 includes two telescopicsections 28, 29,

which turn in suitable bearings 80, 31. The section 28 carries the gear22 and does not move axially. The section '29 constitutes an externalsleeve which is slidable on the section 28 but is suitably connectedthere with so-that the two rotate together. The sleeve 29 is preferablyconnected withthe clutch member2t; by universal joints which compensatefor any lack of exact axial alinement between the shaft sections 28, 29and the spindle 8. To thisendthere is an angularly movable shaft section32' which is connected with-a flange 33 fixed-'tothe sleeve 29 and to aplateBt fixed toflthe clutch member 24:, by means of universal joints35, 36. Casing sections. 37, 38 'arelilrew'i'se fixed to the saidfiangeand-plate and have their opposed ends spherica concaved ends ofcasing sections 39, 40, the opposed ends. of which are cylindrical andreceivedione within the other; and a spring 41 is confined between theselast two sections and tends to hold this flexiblepart at the screw tomove in a straight line.

"Means are provided for shifting the roll spindle T8 axially eitherelectrieallyor :31 hand. The electrical means include a sm l electricmotor 42, which is also carried by the support tend is of a charactersuitable for running in either direction. llt operates through. theconnections for driving the generator 11 and for connecting anddisconmeeting the same with thev spindle. To this end its shaft carriesa worm 43, which meshes with a worm wheel 44, which in turn is mountedon the upper end of a vertical shaft 45 mounted in a bearing 46 on thesupport. The shaft 45 carries at its lower end a bevel gear 47, whichmeshes with a bevel gear 48 on a screw shaft 49. The latter is disposedparallel to the shaft 2i and is journaled in suitable bearings 50, tillmounted on the supporti). llts threads en- 'age with a nut 52 pivoted tothe end of a lever 53, which is fulcrumed at 54 on the support, thelever being slotted at this end because its free end is constrained bythe latermediate its ends the said lever engages a and received by thecollar 55 on the slidable shaft section 29. Obviously anysuitable'shifting device may be employed in place of the lever 53.

Fig. .5 illustrates a form of wiring for startingand stopping the motorand cans ing it to run in either direction. Wires 56, 5? connect withthe field coils, and wires 58, 59 with the armature brushes. When theswitches R and L are in the positions shown, no current passes throughthe motor, which remains at rest. When the switch L is moved against thecontact 60, current passes from the plus line wire by wire 61 throughthe field coils, from wire 57, to wire 62, thence by wire'59 to andthrough the armature in one direction, and by way out the wire 58,switch lit and wire 63 to the minus main. With the switch L in theposition shown and switch It in contact with lid,

the current passes as before through the 1 field coils, but is reversedthrough the armature, so that the motor runs in the reverse direction.Suitable means are provided for operating switcheslt and L. In theparticular embodiment of the invention illustrated the switches R and Lare operated manually. It will thusv be seen that the motor may beoperated to shift the web roll axially in either direction through asuitable reducing gearing acting upon certain of the connections fordriving the braking generator.

The manual means for adjusting the web roll spindle is shown ascomprising horizontal shaft 65 journaled in a bearing on the support-9,a hand wheel 67 on the outer end of this shaft, 'anda bevel gear 68 itsinner end meshing with the bevel gear on thescrew shaft49.

Means are provided for permitting slip to occur in the connectionsbetween the motor 42 and the spindle 8, so that by accident the spindlewere shifted as far as it could go in either direction with the motorstill running, no damage would result to the latter because the slipconnection would yield. lBy locating this slip connection between themotor and the manual adjustinr means, it also permits the spindle to bead justed manually without turning the armature and without encounteringthe d'tiiculty or impossibility of turning the r' from the worm wheelat. Prefer slip connection is between the said wheel and the shaft 45,As shown, worm wheel is mounted loosely on the l end of the said shaft,but is normally tionally coupled therewith by means a s ring 69 whichpresses the worm wheel ownward against a friction member or collar 70 onthe shaft.
